IMPROVEMENT IN PRUNING-ISEEARS The Schedule referred to n'these Letters Patent and making part of the same.

To all whom it may conce-rn: Be it known that I, S. A. MCFARLANE, of Grand Rapids, in the county of Kent, and State of Michigan, have invented a new and usetillrlmprovement in Irnning-Shears and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specilicatioii, in which- Figure l is a side view of the shears, complete.

Figure 2 shows .the shears detached from their handles.

Similar lettersof reference indicate ycorresponding parts in the two gures.

Ihis invention consists iii pruning-shears, the han- I dies` of the blades of which are pivoted to levers which terminate in pointed shanks adapted for entering the ends of wooden arms or handles, and securing the shears thereto in a substantial manner, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

In the accompanying drawings- A A represent two levers, which are pivoted together at a, and which have their shortest arms formed into cutting-shears with curved cutting-edges. Ihe outtingedge of blade b is hooked, and the cutting-edge ot' blade b is convex, thus preventing branches which are in the grasp of these blades from slipping therefrom during the cutting-operation. 'Ihe back edge of the blade l2 terminates at its outer end in a hook, c, which is sharpened and adapted to serve as a pruning-hook.

The longest arms o'f the shear-levers A A are curved inwardly, asshown in the drawings, a-nd connected by pivots e e to the ends of toggle-levers B B, which latter are crossed and pivoted together at g.

The longest arms of these toggle-levers are tapered and pointed, so as to form shanks t' t, that are driven v the shears meet ;v this will prevent injury to the hands in cutting off branches.

I am aware that the. principle of toggles combined with shears is not new, and I do not claim this feature broadly.

I have clected the combination ot' shears and toggles insuch manner that one pair ot levers constitutes the cutters or shears, and a pruning-hook, c, and the other' pair of shears constitutes the spiked shanks by which the handles C C can be securely fastened to the instrument. v

Having described my invention,

What I claim as new, and desire to ysecure by Letters Patent, s-

Ioggle-leve1's A B, terminating in shear-blades b b at their outer ends, and in spiked Shanks/i i, atiheir opposite ends, and otherwise constructed-:unl adapted to operate substantially as described.

In witness that I have claimed and do claim the foregoing, I have herenntoiset my hand and seal this 29th day ot' April, A. I). 1869.

S. A. MGFARLANE. [1.. 8.]
